Eliza is a Londoner who was born into comfortable circumstances (her father being a gentleman), who lived for a time in Yorkshire while growing up. She married James who became a successful solicitor, and lived the rest of her life in north and south London. She gave birth to 9 children, and reached the age of 91, seeing through the whole Victorian period.

From family notes of Mcdonald Beaumont 1934:

"...Your great-grandmother, a Miss King, married Fisher at the early age of 16, a jolly-looking girl, I fancy. They both [i.e. Mrs Fisher and her daughter Eliza Charlotte] lived in Yorkshire for a time, near the Moors and to the authress of 'Jane Eyre', who was so isolated that your grand-mother (Eliza Charlotte) could not concieve how she acquired her knowledge of the world.

Strictly we are entitled to hyphen Fisher to Beaumont, as your grandmother was the last of her race, but we have never done it, and Fisher is not a pretty name. She did have one brother who went the pace and whose death was very sudden indeed, so we did not discuss him much."
